Title: Low current cmos translator circuit
Inventor: CONNELL LAWRENCE E
IPC: H03K12/00
Filed: 1989-06-05
Granted: 1992-06-23
Abstract: ABSTRACT OF THE DISCLOSURE     A low current CMOS translator arrangement is disclosed that utilizes a low current inverting stage, having a peak current requirement, fed by a constant current source at a supply node that also has a capacitor coupled to it. This low current inverter is useful for a number of applications, including generating a sinusoidal signal when it is coupled to a crystal. When one or more are cascaded and coupled to a square wave input signal, the arrangement becomes a low current translator that level-shifts, or translates, the input signal having a first voltage range to a translated square wave output signal having a second voltage range.      In another embodiment called a low current squaring translator, a squaring stage is coupled between the low current inverter and a low current translator that includes one or more inverting stage.s This arrangement is able to achieve an output signal that maintains a precise duty cycle with low noise at a very low current.

Abstract: According to this method, the metal is solidified in a continuous-casting ingot mould consisting of two cooled rolls (2) rotating in opposite directions and arranged opposite each other so as to define a casting space between them, a solidified steel strip (3) is extracted continuously from the ingot mould, and, under the ingot mould, the said strip is subjected to a quenching medium (6) in order to cool it sufficiently rapidly in order to prevent the formation of austenite. This medium may consist of a quenching bath, placed in a container (4) arranged under the rolls (2), and whose bottom is pierced with an opening (5) for the passage of the solidified strip (3). It may also consist of an inert gas in the liquid state sprayed onto the product by nozzles. The steel strips obtained are easier to trim and to coil on exit from the casting line, by virtue of the absence of martensite in the ferritic matrix.
